"""Runs the plain-node numpad.js behaviour test (tests/js/test_numpad.js).

There is no browser/JS test harness in this project yet, so this is a thin
pytest wrapper: it shells out to ``node`` and asserts the script's own exit
code. Skips (does not fail) when node is not installed, since numpad.js's
logic still gets exercised by whatever picks this up where node is present.

Covers gitea:Adriano/TieMeasureFlow#11 and #27.
